Submit a signed message to verify wallet ownership. The user must have signed the exact verification message provided by add_wallet. When collecting the signature from the user, remind them to paste the full signature hash from their wallet. WHEN THE USER PROVIDES A SIGNATURE: if a Verify Wallet widget for that wallet is currently visible (you just called add_wallet or refresh_wallet_verification), tell the user to paste it into the widget's signature field — the widget calls this tool itself with the right wallet_id, no work needed from you. If no Verify Wallet widget is on screen (e.g. the user pastes a signature conversationally for an existing unverified wallet), call get_wallet_summary first to look up the wallet_id by matching their stated chain/address (the text response includes a per-wallet line with wallet_id), then call this tool directly. Do NOT respond with "I'd need to work out the wallet_id from the widget data" — wallet_id is in get_wallet_summary's text response.
